Patent GB-2236712-A (GB)
Title: Cleaning ink-jet printheads by flushing.
Inventor: WEINBERG HILLAR
IPC: B41J2/17
Filed: 1989-10-11
Abstract: To flush ink out of the ink gun 15 of an ink jet printer, it is connected to a suction source 23 (normally used for gutter suction) through a purge line 33, purge valve 35 and gutter valve 27, while the ink feed line 13 is connected to the solvent reservoir 17 through a feed valve 11 and a flush valve 37. This draws solvent from the solvent reservoir 29 into the feed line 13 and the ink gun 15. Then, the purge line 33 is isolated from the suction device 23, and the feed valve 11 connects the feed line 13 to a supply of ink pressurised by ink pump 5. The pressurised ink is driven into the feed line 13, driving some of the solvent already in the feed line and the ink gun 15 out through the nozzle of the ink gun 15. The ink flow is then stopped before fresh ink reaches the ink gun 15. This avoids ink drying in the ink gun 15, blocking the nozzle, while the jet is not running. By delivering solvent along the ink feed line 13, and using the suction device 23 and the ink pump 5 to drive the solvent, instead of providing a solvent pump and a solvent line, the complexity, bulk and heat generation of the ink system are minimised.

Title: Ventilating fan with shutter
Inventor: YU KUN LUNG
IPC: F04D25/14
Filed: 1990-03-15
Abstract: Undesired air flow into the air passage of the ventilating fan is controlled by a shutter (5, Fig.2) which is installed on the outdoor side of the ventilating fan to close or open the air inlet passage of the ventilating fan. Both the ventilating fan and the shutter, along with cooperating air-conditioners, are controlled by a controller 2 which operates in accordance with the indoor and outdoor temperature sensed by sensors 27 and 28. The controller operates so that when the temperature of a room in which the fan and air-conditioners are installed is lowered to a level determined by a low temperature setting the controller will power the fan and open the shutter to allow air into the room. When the temperature of the room rises to a level determined by a high temperature setting the fan is switched off and the shutter closed; when the outdoor temperature is lower than the lower temperature setting the air conditioners are shut down and the fan activated and shutter open to draw air into the room. <IMAGE>

Title: Electronic magnetic compass
Inventor: NOMURA GORO
IPC: G01C17/38
Filed: 1990-12-14
Abstract: An electronic magnetic compass which is to be mounted on a small ship and which has reduced cost and improved performance comprises a sensor section (1), e.g. including a magnetic toroid wound with energisation and pick-up coils (Fig. 2 not shown), to produce a signal indicative of the direction of the earth's magnetic field and which is used to drive a compass card (8) to provide a corresponding indication. An angle sensor (9) is interlocked with the compass card (8) so as to produce a feedback code signal at predetermined angles only, a code converter (10) converts each code signal into a compass indication angle, and a signal conversion circuit (4) produces a deviation signal indicative of a deviation between an azimuth angle signal and an indication angle signal. The compass card (8) is driven by a simple open loop system between the predetermined angles, and the structure of the angle sensor is simple and the cost reduced as compared with a continuously operable closed loop system requiring an encoder disc with fine resolution over the full 360 DEG . The azimuth angle signal and the indication angle signal can bed automatically calibrated so that measurement accuracy can be improved, e.g. to allow for field distortion by the vessel. <IMAGE>
